ComfortPro® Lithium Ion Electric Auxiliary Power Unit

The ComfortPro® electric auxiliary power unit (APU) with li-ion batteries (250ION) significantly outperforms conventional electric APU runtime and battery life, providing quiet, emissions-free performance with minimal maintenance.

Features and Benefits

Advanced Li-ion Technology: The ComfortPro® electric auxiliary power unit (APU) with li-ion batteries (250ION) significantly outperforms conventional electric APU runtime and battery life, providing quiet, emissions-free performance with minimal maintenance.

Less, Yet More: Using proprietary power-management technology, two li-ion batteries do more than the work of four AGM batteries, achieving 17 hours of continuous air conditioning under certain real-world conditions, the longest of any electric APU. That’s double the runtime of some competitive models and 50% more runtime than our AGM-battery model, while trimming APU weight by 26%.

Purpose-built Batteries: Advanced li-ion batteries are engineered specifically for APU applications. An extremely power-dense and durable solution, they charge faster and experience less power degradation over time compared to conventional batteries. Warrantied for worry-free performance for five years, outlasting some fleet trade cycles.

Fuel Savings: Fuel savings and compliance with anti-idling regulations are immediate as soon as the truck engine is shut off and the ComfortPro electric APU is turned on.

Low Maintenance System: With few moving parts compared to diesel APUs, ComfortPro electric APUs minimize maintenance expenses.
